Abstract

PURPOSE: A subway air quality monitoring method and a system thereof for immediately informing a pollution level which an air quality sensor senses to an administrator using an SNMP are provided to keep the fresh air in a subway station by reflecting the air pollution of the subway station after measuring the air pollution degree of the subway station by using SNMP. CONSTITUTION: A sensor(160) is connected to an SNMP(130) to the wire. If on-off output is detected, a trap circuit of the SNMP informs air pollution to a main server(140). The main server compares the air pollution degree with a standard air quality of environment office. The main server informs the compared result through SMS to administrator.

Description

Subway air quality monitoring method and system using SNMP {Subway air qualitative watch method and the system which use SNMP}

The present invention relates to a method and system for monitoring subway air pollution using SNMP. More specifically, SNMP is used to monitor the air quality in the subway station in real time to determine whether the air quality in the subway station meets the EPA standards, and to monitor the air condition inside the subway station by reflecting the air pollution. It is about a notification system.

 A method of monitoring subway station air pollution level, the method comprising: (a) Receiving an internal air pollution level from an air pollution sensor module inside a subway station using Zigbee; (b) Transmitting from the Zigbee to SNMP (c) Air quality management Determination of conformity based on the criteria (d) (c) provides a method for monitoring the air pollution in the subway station using SNMP connected to the staff after determining whether to send SMS from the main server.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As the number of subways increases, the number of passengers living in underground spaces also increases, and public health is becoming a concern for citizens, and the double doors of the platform are installed (safety, dust, train wind (wind generated when the train is operating)). In this way, while the subway station is in an environment free from pollutants, the ventilation system only inhales outside air, and the pollution level is high during subway operation.

The air quality inspection of subway is carried out by AirMetric (US), but the air pollution of the filter is fast and there is a problem in measurement, so it is more advantageous to use the Zirconium-type sensor. You can increase it. In addition, sending data via SNMP using Zigbee is advantageous for simple data transmission and reception.

In order to achieve the above object, the present invention provides a sensor module for detecting the subway station air suction, Zigbee module for transmitting the detected data, SNMP module for sending the received data to the MIB, all of the data compared to the database, The main server to notify, the system containing the program to send SMS from the main server to the person in charge

The present invention as described above can immediately notify the administrator of the pollution level detected by the air quality sensor, the subway users can know the current air quality of the subway history.

Hereinafter, with reference to the accompanying drawings an embodiment of the present invention in detail as follows.

1 is a block diagram of the present invention, (130) SNMP is connected to the wire (160) SENSOR by wire, the TRAP circuit of (130) notifies the air pollution to the main server (140) when it detects the ON-OFF output. 140 is a system that notifies the manager to (150) SMS compared to (170) Air Quality standards.

At this time, the (110) ZIGBEE can also be parallel to the method of transmitting the (130) SNMP roll using the RF, the sensor and ZIGBEE is configured in one piece.
